The Institute of the Estonian Language is pleased to host a conference entitled ‘Colour Language and Colour Categorization’ (CLCC) on 4-7 June, 2013 in Tallinn, Estonia. The conference aims to bring together linguists, psycholinguists, psychologists, cognitive scientists and cultural anthropologists studying colour language and colour categorization, as well as their underlying cognitive processes. The event endeavours to create a forum for scholars to explore how we talk about colours and how we often categorize them in language and the brain across diverse languages and cultures, as well as to discuss the future of colour research.
